REEL.

Application filed July 12,

To all whom it may concern:

Be it known that we, LAURENCE S. Lacu- MAN and EDWARD FtLn'A, citizens of the United States, and residents of New York. in the county of Xew 'York and State of New York, have invented certain new and useful Improvements in Reels. of which the following is a specification.

Our invention relates to the construction of metal reels particularly adapted for motion picture films.

The object of the invention is to provide a strong reel, light in weight and one which will withstand the rough and hard usage to which reels of this class are subjected.

The reel is constructed mainly of wire, preferably round in cross-section, so arranged and secured together that the reel,

although of skeleton form will have great rigidity.

A further object is to so secure the'sleeve for the supporting spindle by which the reel is rotated that it will not become loose due to continued use of the reel.

A further object of the invention is to securely fasten the wires forming the side members of the reel to the'hub in a simple manner.

The invention consists in the construction of metal reel hereinafter more particularly described and then specified in the claims.

In the accompanying drawings. l* ig. l is a side elevation of a metal reel constructed in accordance with this invention.

Fig. 2 is a transverse section taken on the line 2--2-Fig. 1.

Fig. 3 is an inside view of one of the side members for the reel.

Fig. 4 is an enlarged side elevation of the hub barrel.

Fig. 5 is an end view of the same.

Figs. 6 and 7 are side elevation and end view respectively of the supporting spindle sleeve.

Referring to the drawings. the reel comprises two side members forming the side plates for holding the reel against edgewise displacement in the reel. Each of these side members consistsof a continuous peripheral ring 1 preferably of round wire and a plurality of wire elements 2 which join the peripheral ring to the hub in a manner to be presently described.

By forming the periphery of the reel of round wires liability to injury to the hand of the operator upon attempting to stop the 1920. Serial No. 395,453.

rotation of the reel by pressure of the hand is reduced to a minimum as compared with reels havingsheet metal disks for the side members.

3 indicates hub plates or disks to which the wire elements '2 are secured. The wire elements 2 fOl'.0tl (l1 said member consist of wires suitably secured by welding to the wire rings and disposed at the point of attachment in a plane thereof so as to ofi'er no lateral projection either inward towards the film or outward. They extend from the point of attachment or connection inwardly toward the center and are there suitably secured together as will be presently described, the two side members thus formed being joined to one another by a hub to complete the construction of the reel. They are preferably so proportioned and formed that they make side contact with each other and with the inner surface of the peripheral ring 1. At these points of contact. indicated at 4, the. parts are firmly secured together preferably by the electric welding process.

The elements 2 have free ends 2 which contact with and intersect an annular ridge .3 formed on the hub plates 3. At such points of intersection the wires 2 and plate 3 are electrically welded together by means of the ridge Preferably but not necessarily the free ends 2' of adjacent elements 2- are spread apart for the purpose of providing a sort of truss structure; thereby greatly increasing the strength and also to provide. if desired. a repository for locking means to be presently described.

Thus each side member of the reel consists of a peripheral ring 1, and Wire elements 2 welded inside of the peripheral ring and disposed wholly within the rings being suitably joined together in the hub or center of the reel and the two side members being connected in the hub to complete the con struction.

6 indicates a cylindrical hub barrel prefer ably of sheet metal. The barrel 6 is provided at both its ends with a plurality of longitudinally projecting tongues 7 (see Fig. 4) spaced apart around the ends of the barrel. The tongues 7 enter the space between the spread apart ends 2' of the elements 2 and are turned over against the outer surface of the hub plates 3 as indicated in Fig. 1. thereby locking the side members and the hub barrel together. Preferably the tongues 7 also fit in grooves or seats 8 formed in the periphery of the hubv plates 3. When the parts are assembled the wire elements 2 are disposed in notches or seats 9 formed in the ends of the hub barrel whereby they are firmly supportedin place and also permit the end of the hub barrel to abut against the inner surface of the hub plate and lnake a closed joint. It is not necessary that the tongues 7 engage the hub plate between the spread apart ends 2' as they might be disposed at other places around the periphery of the hub plates butby arranging them as shown they are in such position that the sharp edges of the grooves 8 will notbe apt to injure a persons finger should the reel be picked up by grasping" the periphery of the hub plates when the reel is empty.

The hub plates 3 are provided with a central opening 10 "for the supporting spindle and also with a key-way 11 so that the reel can be rotated by the spindle. 12 indicates a sheet metal sleeve for the spindle. said sleeve passing longitudinally through the hub barrel 6 from one hub-plate 3 to the other. The sleeve is provided with a longitudinal key-way 13 corresponding with the key-ways 11 in the plates 3. In forming the sleeve 12 of sheet metal the edges of the blank are turned up to provide flanges 11. These flanges are cut away at each end of the sleeve to form a shoulder 15 at each end.

In assembling the two side members of the reel to the hub barrel 6, the sleeve 12 is placed between the hub plates 3. the ends of the sleeve and the key-way 13 fit in the holes 10 and keyays 11 ot. the plates 3. The hub plates 3 butt against the shoulders 15 and in this way when the hub' plates 3 are locked to the hub barrel 6 by the tongues 7 the sleeve 12 is securely held in place without not relatively move in any direction.

By so forming and securing the sleeve 12 the necessity of securing it in place by turning over the ends against the hub plates (as has been most commonly done in the past) is avoidedf The serious objection to the old practice is that the reel rotates against a fixed'supp'ort and in a very short time the turned ovcrends of the sleeve are worn away and the sleeve becomes loose and drops out of the hub.
